"It is correct to say this in theory, but it still needs to be practiced."

Guan Heng said as he picked up a crystal and continued to say, "For example, we need to study the structure of this crystal and why it can control the self-destruction of the evil spirit body, etc. In my opinion, we still need time to continue to understand it."

"Oh, that is to say, you can't know how to use the blue crystal immediately? What a pity." Ruotao said at this time: "I also want to see if I can control the evil spirit to explode."

"You don't have to worry about this. We have enough blue crystals in our hands. Are we still afraid that we can't find the way to let the evil spirits explode themselves?"

Guan Heng smiled slightly and then said, "It is not impossible to capture a few evil spirit kings at will, and you can continue to experiment until you can achieve perfection."

"Yes, the young master's words make sense, there is no shortage of experimental materials at all." Ruotao smiled and said, "Because we can find a large number of evil spirits on the road."

"Yes, those evil spirits have no other use anyway. They have three functions. First, they are eliminated when we pass the boring time; second, they are refined into soul power."

Gu Sangnu said with her fingers: "This third one is used as a test subject. It is also a waste use, right?"

"correct!"

“Incisive!”

"It's so correct." The sisters agreed, agreeing with this statement.

At this moment, Guan Heng found that the skeleton spirit that followed him was whimpering and said, "Do you want to get some more spiritual energy? Okay, I'll give it to you."

"Swish!" As soon as he finished speaking, Guan Heng bent his finger and released some spiritual energy. He curled up in front of the other side. The skeleton spirit immediately began to absorb this aura.

"It seems that this guy really likes pure spiritual energy." Qing Huang looked carefully from the side and said: "When we adopt the corpse spirit, we can also refer to Aheng's feeding method."

"It's right." Yan Xin smiled beside him, "Where is Guan Heng, he can always attract those strange little things, such as spirits, souls, and various creatures, and it is easy to follow him."

"Well, princess, I just think that you are praising me."

Guan Heng said lightly. At this moment, the skeleton spirit had eaten up all the spiritual energy. It flew to Guan Heng again and screamed. Ruotao next to him asked: "Young master, what is this guy talking about? Did he want to eat it again? That's really greedy."

"No, you misunderstood it." Guan Heng held the skeleton spirit with his hands and said casually: "This guy knows that we are collecting blue crystals and intends to take us to find those who know where they are."

"What? Are there any remaining crystals?" Everyone was surprised when they heard this.

"Well, and according to the information expressed by the Bones Spirit, those crystals should be concentrated together, and most of them were not swallowed by the ancient lizard."

Guan Heng said at this time: "In other words, we have the opportunity to see larger blue crystals, and even their minerals." After that, he said to the skeleton spirit again: "You come and lead the way."

"Wuwuwu—Wuwuwu—" It was said in a time, and soon, the spirit suddenly soared into the air, and then flew towards the area in front of the left, Guan Heng and the others followed.

Not long after, everyone came to the area where a large number of blue crystals were hidden. This place was located in a remote and dim corner. If you don’t observe carefully, you will never be easily discovered.

"Bang bang bang!"

"Boom!"

"Crazy!"

In the lightning and fire, the rock walls were completely shattered, and countless earth and rocks flew everywhere. When the dust disappeared, everyone saw everything inside - the mountain of blue crystals. Although most of them had consumed all their spiritual energy, many of them were full of spiritual energy.

Guan Heng suddenly clapped his palms, "Bang!" In an instant, applause resounded in every corner around him, just as everyone was wondering why Guan Heng wanted to do this.

The "crackling" sounds came one after another, and the blue crystals in the surrounding empty shells that were gone were suddenly shaken and trembled, instantly turning into powder!

It turned out that Guan Heng just used the echoing impact of applause to shatter the empty shells, which saved a lot of time in searching for useful crystals.

"Wow, this blue crystal several feet long is rare before." As he said that, the demon lord had already raised this thing and said to everyone with a smile: "There is also a lot of spiritual energy inside."

"Well, it seems that this area is full of similar blue crystals. Please collect it and then let the toad be put into the ethereal toad tripod."

While saying this, Guan Heng glanced around and then asked the skeleton spirit who fell on his shoulder: "Where do you want me to see?"

"Woo woo woo woo--"

Hearing Guan Heng's inquiry, Bo Ling immediately whistled and rushed forward. Guan Heng immediately followed him, and at the corner several feet away, there was a stone platform more than a foot high. Because it was in a dim corner, everyone did not notice the existence of this place when they came here.

"Is it the corpse of the ancient lizard again?" Seeing the huge corpse of the ancient lizard lying on the stone platform, Guan Heng walked forward, just glanced at the corpse, and then smiled slightly: "Hmph, I seem to understand."

"What do you understand?" the sisters who followed him asked one after another.

"The corpse of this ancient lizard should be the king of the ancient lizard clan." Guan Heng glanced at the corpse and said, "Unlike ordinary ancient lizards, it does not devour a small crystal, but a huge crystal that is almost half the size of its own body."

"What?" Hearing this, the girls took a breath of air. Then, Ruotao asked, "Young Master, why do these ancient lizards devour crystals?"

"I have been thinking about this reason. Now, I can guess the general reason." After that, Guan Heng hooked his finger at Ruotao: "Give me one of the crystals you just brought."

"Yes." While agreeing, Ruotao placed the small crystal stone in Guan Heng's hand.

"Huh!" He said it, and soon, Guan Heng suddenly released a stream of ice and mysterious spiritual energy to cover the blue crystal. "Glala!" The cold air immediately covered the surface of the crystal.

"Bang!" But the next moment, the ice layer cracked and shattered, and fell to the ground in an instant. Guan Heng said, "I understand, this is why the ancient lizards swallowed crystal stones into their abdomen."

"Uh, this is..." Seeing this scene, the demon horn and the unicorn ice dragon saw the special state shown by the crystal, and immediately shouted in unison: "Can the ability to weaken the cold air and even offset it?"

"That's right, that's it." Guan Heng said: "The ancient lizards who had no ability to resist the cold attack and could even sit and wait for death. The last line of defense was the crystal that was swallowed into their stomachs."
